Eureka offers every station in a city identical coverage. I'm pretty
sure IBOC was invented mostly to prevent the adoption of Eureka in the
U.S., and the resulting ability of low-power, AM, and daytime-only
stations to develop a full-fidelity, full-time signal able to compete
with the high-powered FMs.

The local NPR station (KUOW) had an hour with their engineering staff
on one of their talk shows last summer when they started using IBOC.
One of them said, directly, that the National Association of Broadcasters
opposed other digitial radio systems because they doubled the number of
available channels.
